Hey all, my first post here. I just ordered my DNA, it's coming pre-rooted and S-OFF. I want to flash the Unofficial AOKP 4.2.2 port, but heard some rumors about GSM not working. I'm a Verizon customer, but I'm travelling to Germany for a few weeks soon. Do I need to flash the GSM patch I read about, or will that mess up my Verizon connection? Thanks in advance!

Flash the gsm patch when you leave, dirty flash the ROM when you get back for Verizon service.

If you are using a local SIM then yeah, need the patches with all the right information for the carrier you are using, better even to get settings from the carrier directly when you buy your SIM. Some places will do that for you. However, I get poor signal and battery globally on non-stock ROMs though.
If you use the Verizon global plan like me then stay stock rooted. I get better performance out of mine that way. Main reasons for me, battery lasts longer and I get better/faster signal.
Global Radios work great though, better than my Fireball (Incredible 4G). Currently I am in Belgium and have minimal signal but it's way out in the country east of Genk. I had great signal in Dusseldorf, Aachen and other parts of western Germany last week though. Works well all over Netherlands too. Only issues were in France this weekend when it took over an hour to get a data signal but after a reboot it worked fine.

So I am leaving Montana for south Korea soon and was pretty excited to learn that my Rezound is global capable. The only thing is I am unsure if it will work on a Korean SIM card, or how to do so. I am s-off running the first leaked ics ruu. Do I need to ruu to the global firmware? Or will any gsm capable roms work without a firmware update? Also, if there's any one out there who has been to south Korea and could give me some tips on providers to choose from it would be appreciated.

You need to install the official Global RUU, leaks can be problematic because they prevent you from getting OTAs on stock rom and may not be the latest, most stable software.
I think there have been like 2 official firmware upgrades and several leaks between what you are running and global.
You do need a GSM enabled ROM, and one that is based on the global firmware. Simplicity or Newts One XXX 5.08 may be good options for you if u want to stick with a Sense ROM.
You may still need to call Verizon re: international calling, although I wouldn't mention I was rooted.

Thanks for helping. I was a little unclear in my original post however; I actually am running Newts One XXX 5.1.0 currently (awesome by the way). What I am wondering though is this; will the fact that I am not on the global firmware mean that I will need to RUU update in order to get service with a South Korean provider. I do not plan on trying to remain with Verizon as I will be in South Korea for more than a year.

rezound in rok
I'm also heading to the rok and hoping to use my rezound. I'm on stock ics ota. I'm going to see what I get on a stock rom before I do any unofficial releases, but I expect to drop SMS capabilities or maybe data like you see in the states with a T-Mobile sim in. I arrive in Korea on the 31st so I'll update sometime late next week and let you know. I've been to Korea before and I believe we will have to go with SK Telecom as our carrier because it is the only GSM network. The other networks are cdma to the best of my knowledge. Hopefully my next update will be from my phone on a Korean network!
Rezound in South Korea update
In Korea now. I just flashed my phone from a stock OTA ICS, unrooted, s-on over to the Global RUU found on Androidpolice.
I have tried to buy just a sim card from several stores, SK, KT Olleh etc, and the stores all say that I have to go to the headquarters stores located in Seoul, Yongsan Train Station on the top floor. Apparently this is the ONLY way to get a sim for a global phone, other than having a korean national get one for you and give it to you. This weekend I will be going to the headquarters stores and getting a sim, Other problems you may run into are related to being a foreigner in Korea. They will sometimes not want to sell you a phone on a contract because you as a foreigner could disappear at any time without paying the bill. So, they will try to get you to buy prepaid. I don't want to deal with prepaid anything, but that may be a viable option to get a SIM card easily. Just buy a reallllly cheap prepaid phone that has a sim in it, pull the sim and throw it in your global enabled device. Unless you speak Korean, navigating to the headquarters and getting what you want may prove a bit difficult. Fortunately, I do speak Korean, so I will let you know how it goes.
I will update again once I actually have a Sim in my phone!
Thanks for the valuable information so far. I will be arriving there at the end of November and am looking forward to hearing more about how It's going for you there.

got a sim, no data!
Finally got a sim from KT Olleh today. The girl at the counter didn't believe me that the phone would work, but I got her to do it anyway. By the way, don't try to set up service for a phone anywhere in Korea on a weekend. They cannot activate a new phone unless its a weekday. So anyway, got it all setup and the girl sits there and plays with my phone for a while without saying anything to me. Then she tells me that the calling and texting is fine but the phone won't get a data signal. I asked her to set the APN, and she said she did. I checked it out and she had put in the KT APN as alwayson.ktfwing.com Looks right to me, and she seemed to know what she was doing for the most part. Then she started to go on about how Korea runs on CDMA for the most part and not GSM yadda yadda.
So, I have a Rezound, working for incoming and outgoing calls and text on KT Olleh, but no data signal at all. I might repost a similar message in another forum topic to see if any gurus have any advice on how to get it working. Also going to do some more research. I'm new to this but there is tons of information out there. I will post again once I have resolution or give up and buy a new phone!
PS Phones in korea can be REALLY expensive. Dropped 850 on my wifes LG phablet (optimus VU2)!!! Equivalent to the instinct in the states I think?
didn't flash twice
So, I am a phone noob, and did a lot of reading last night. Saw that most people flash rezounds twice anytime putting on new firmware etc. I think I will try that tonight and see if I pick up the data signal.
The ruu's generally need to be flashed twice. However I did not need to do so going to the global, the ruu automatically took care of everything.

Some helpful information that KT Olleh has to say about using a non-korean phone in Korea.
http://expatblog.kt.com/71
The rezound may not have the radio frequency that network uses. That would be the main problem as to why you aren't picking up data.

I am currently in Seoul and have rented an Evergreen Mobile Sim Card that works on KT Olleh's network. I am curious as to whether you were ever able to get your Rezound to work with their Data network, and if so, how? Mine works with Olleh Wifi for free but will not even recognize the 3G, despite my having changed the APN settings, and even going to the Evergreen Mobile office in Yeoksa-dong today (they said they couldn't get it to work after an hour of fiddling with it themselves).
Suggestions? Do I have to root?
Oh, and the link in your above post has expired. Could you summarize what KT said?

It's kinda hard to answer which modem you need without some more details. It's also a personal preference based on where you live. Some modems/radios work better in certain areas than others. What network are you on, AT&T? I'm on AT&T and heard the latest modem for our i717 is the i717UCMB4. You can flash that one in recovery. I used it and it works but for some reason the i717UCLD3 modem is working better for me. I got that modem when I used odin to install this rom, then flashing my favorite rom on top of it. Some people say the UCLF6 modem works better for them. You can get that one here and flash thru your recovery. Sorry I can't find the i717UCLD3 flashable zip. Maybe someone else has a link so you can flash between all 3 and see what works out best for ya.
No need to do any modem flashing. LF6 is the latest and greatest modem available.
Updating.....AT&T released 4.1.2 and a new baseband/modem which can be found here http://forum.xda-developers.com/showthread.php?t=2261713 and is flashable from custom recovery.
I'm testing out a possible switch to T-Mobile. Had AT&T unlock my phone today and got a prepaid T-Mobile SIM in it. I'm getting H+ (LTE?) speeds while doing data transfer and then it drops back to 3G when data isn't being used heavily. I'm on UCLF6. Although I've had this phone for a year, installed tons of ROMs, compiled my own kernel, etc. I'm a noob when it comes to modems and have just used whatever worked. What's the advantage of using a "T-Mobile" modem if UCLF6 seems to be working on T-Mobile anyways? Do you get more speed out of it?
I don't want to lose AT&T compatibility yet as I just got the prepaid T-Mo to test out (been getting crappy reception with AT&T at work and tired of the expensive plan of minutes I don't use). If T-Mo improves my speeds at work I'll probably just pay to cancel my AT&T contract and transfer my number, but for now I'm just testing.
Well I am not sure about the baseband/modem issues on T-Mobile but most important would be the GSM Bands/LTE are compatible. As some AT&T phones don't support 3G/LTE frequencys T-Mobile use. If you are using a prepaid SIM it may not even support LTE for example Straight Talk on AT&T supposedly will only use HSPA+ .
Well I have 2 unopened Samsung Alphas sitting in front of me.
1. SM-G850F (International from Germany)
2. SM-G850M (Unknown Origin)
I have Many sim cards that i am using. But the main one i want to use is the T-mobile USA.
What i have gathered reading is the F has the custom recovery where as the rest A,W(QuadCore) Y(Asia ?) do not.
All of them seem to have Root.
Version A is tuned for AT&T
Version W is tuned for T-Mobile USA LTE (But is a Quad)
etc etc
But the info on the M Bands is very vague, as in the Band listing on the website is always different listed for the M.
So what are my advantage of picking one over the other (M of F) for T-Mobile USA ?
As far as i know every other version than the A has exynos chipset with the octa core cpu and the A has qualcomm with quad core cpu and thats why almost every other version has root and the A dont.

Why the hell are they doing this ...
So how different is the M from F ?

But it seems that you should have the

needed with the M Version.
Are you getting full performance on 3G , 4 G and LTE on your Alpha ? ?
Yes i am getting all bands 2g 3g 4g H+ LTE depending where i am at sometimes E. Though during a call i only get lte or h if non of those my data doeent work during a call

Can you tell me if the G850M is carrier-branded in any way? I know the G850F isn't, and I was wondering if the same is true for the G850M. Basically, I would like to receive Android updates directly from Samsung without carriers getting in the way, and I would like free use of the Portable WiFi Hotspot/Tethering feature (even without having it as part of your plan). I know Nexus phones allow you to do this.
Thanks!

850M is not carrier-branded...it's unlocked and sold by Vodafone. I rooted mine, so can't get updates through Samsung anymore.
I did use it to create a Wi-Fi hotspot to tether my laptop. It works well, and I do not pay extra for this feature on ATT.

Thanks very much for your responses! I greatly appreciate it.
I found a 850M on eBay for $89.99 couldn't believe it, excellent condition like new. I rooted it, installed another XDA members 4.4.4 ROM but couldn't notice any difference from stock, works fine on Cricket (At&t) prepaid, 4G same speeds as my previous S5 Mini At&t version phone, around 8mbps down, 4mbps up, half that when on a call. I cannot find many 850M's on the market, it's amazing. I want to buy at least 1-2 more, these are one of the best phones Samsung produced, especially one of the last good phones with removable battery! There are more 850F's on eBay but may not have as fast data with At&t as they are EU version. After my experience with S5 mini on 5.1.1 ROM I noticed much faster battery drain and prefer 4.4.4 performance. Hope my post helps someone=) -Aje

However I didn't notice any difference from the stock ROM, was surprised to see the same original games included which I consider bloatware. Anyway the phone works great after rooting and uninstalling a lot of things, although it did suddenly crash and restart yesterday while on a phone call, first and only time in about a week I've had it. I love this phone and the size is perfect.
Really wanted to try this ROM but DL link is no longer working and no one is replying lately.

If the problem persists on the stock ROM (as well as GPE), you might have a radio that isn't fully compatible with your local carrier.
Do you know what HSPA (3G) and LTE bands (if applicable) your carrier uses?
Also, you might shut off LTE and see if that helps (not possible on stock AT&T ROM).
Am thinking I just S-Off and flash GPE to see if the problem persists. I am on a GSM carrier, have owned several At&t devices before with no problem at all. Switched off 4G LTE and problem still persists. could the problem be hardware?

Sure, a hardware fault is "possible". But you can't attribute it as "possible" without some more research or troubleshooting.
The fact "several AT&T devices" work on your network is slightly irrelevant. Every device has its own set of specs and band compatibilities. You should verify that your network's bands are supported by this particular device (AT&T version), first of all.
You should also consider if the seller will honor any return or exchange before you s-off the phone (such mods which would almost certainly void any return policy by the seller). But if you are not eligible or interested in returning the device, then yes, trying different ROMs or radios reasonable troubleshooting steps.
Every time I flash a custom ROM based on 4.16.X firmware I either lose LTE (though HSPA+ still works perfectly) or the ability to receive calls. I've tried ARHD, SD, the Stock WWE, and the US DEV edition, and all of them have exactly one of those issues (it's never both). I'm currently back on ATT stock 4.4.4 ROM (3.42.502.1 firmware), rooted, S-Off.
I thought flashing the WWE RUU before flashing a ROM like ARHD would be enough to upgrade the firmware, but maybe I'm missing something.

WWE RUU indeed updates the firmware, however to the WWE radio and other firmware.
I think a couple things are going on here (assuming your are on AT&T's network):
1) A number of folks have reported call issues while on AT&T's LTE network and running WWE based custom ROMs. The suspicion is that the changes being made by AT&T in advance of HD Voice (Voice over LTE) deployment is not playing well with Euro based ROMs. AFAIK, there doesn't seem to be a fix for this, although I think some devs like Team Viper are looking into it.
2) US Dev Edition is intended to be used on AT&T's network. However, its not clear from your description, but it seems you are using the WWE firmware (radio probably most importantly) with the Dev Ed ROM. If you haven't already, try the Dev Edition firmware with the Dev Ed ROM; either by RUU or flashing the firmware separately. That is the configuration I was running until just last week (giving Sense 7 a try) and seemed to have no issues on AT&T, including travel to a couple different locations around the country.

If you don't mind wiping the phone (backup any personal data that you want to keep before RUU, obviously), then yes that is probably the easiest way to do it.

EDIT:
So I actually got a call to come through. When it did, LTE went away and wouldn't comeback, so it definitely seems like an issue of VoLTE compatibility, even on the Dev Edition ROM for me.

Weird. I wouldn't think that you would have the issue on Dev Edition ROM, running Dev Edition firmware.
Can you confirm the RUU properly installed the Dev Ed radio, by stating your radio number?
Forgot to mention that turning off LTE is a workaround. But obviously less than ideal.

I confirm that is the correct US Dev Edition radio baseband.
Weird, I've used mine (as mentioned) not only in my home area of Boston (and surrounding areas) but also while travelling to North Texas, and Washington State, and didn't see any issues. But that is by no means exhaustive. We really have little way of knowing what changes AT&T is making to their LTE network and where (in preparation for HD Voice).
You might fall back to the AT&T 4.4.4 ROM (and even the corresponding radio) to see what will happen. But that's of course kind of disappointing to fall back to KitKat from Lollipop.
You can even try the WWE firmware (4.16.401) zip. But I'd be very surprised if you get a better result on the WWE radio versus the Dev Edition.
